IMPRovED CAR-coUrLING.

The Schedule referred vtojn these Letters Patent and making part of the same.

. i To all whom @t may concern:

Be it known that we, JOHN M. WHEELER and CHARLES W1 CHASE, 'of Batavia, in the county of Jefferson, and State of Iowa, have invented a new and useful Improvement in Car-Couplings or Buffers; and we do. hereby declare that the following is-a full, clear, and exact description of the saine, reference being had to the annexed drawings, making part of this specification, in wl1ich Figure l is a longitudinal vertical section, through the centre of A of tig. 2.

Figure 2 is an elevation of two buffers, shown as coupled together, the coupling-hook and -link being shown in dotted lines.

Corresponding letters represent corresponding parts in both figures.

This invention relates to that class of car-connections known as self-couplers, and

It consists in the combination and arrangementof its parts, 'as will be more fully explained hereinafter.

A represents a buffer, which may be of cast. 01 wrought-metal, and it is to have a recess or chamber formed in its centre, for the reception of the couplinghook C. It also has an opening through its front end, for the insertion ofthe coupling-link.

A', -in' fig. 2, represents a buffer as coupled to A in the same ligure, and shows how the same may be used to couple two cars together, one of which is supplied with our improved coupling, while the other has only` as shown'at a, igs. l and 2, where it is seen as hav ing its forward end, or' a hook formed thereon, passing through the aperture formed in the coupling-bar or link, and resting in a recess formed in the lower portion of the buffer, while its rear end rests upon a spring, as shown in fig. 1, the object of which is to prevent the hook from rising out ofthe link in consequence of the jars or coucussions to'which the cars are subjected while in motion.

The arrangement of this hook within the bu'er is such, that as the force is applied to move thepcar, the hook will be drawn forward, in consequence ofthe yielding of `the spring G, until its i'ont end cornes in cont-acnwith the projection on the end of the bnffer, when the entire force will be exerted upon the spring, which may be attached to the inner end of such buer.

D represents the coupling-bar or link, which isV to be constructed with an aperture in its front end, for

the reception of the hook of the buffer, or the hooks of both buffers, when both are supplied with such hooks.

At a short distance from the aperture or opening above described, there is to be formed another aperture, which may be a hole bored through the link or bar, or it may be slightly elongated, it being for the reception of the coupling-piu, when suchdevice is used..

That end of this link or bar which is opposite. tothe one. just described, is to be solid, or without apertures or openings, for the purpose of making it heavy, or constituting it a weight, so that when it is drawn out of the buffer, it sha-ll at once fall down to and rest upon the lower portion of the buffer, which will form a fulcrum for the link to rest upon, which will cause its inner end, or 'the one which remains in the buffer, to he raised, and thus all dangerof the bar being jarred or `shaken out of the butler will be avoided.

E represents a rope or chain, which is to be attached tothe upper side of the coupling-hook, and is to pass up through a slot or aperture formed in the upper wall of the buii'er, and may extend to the top ofthe car, if desired, it being for the purpose of raising the hook out of the link when it becomes necessary to uncouple the cars, or to remove the link. or bar from the buffer.`

F represents a rubber or other spring, which is to be placed under the rear end of the. hook, and held iu its position by means of a plate of metal, which -is to be secured to the under side ofthe butter, the object being to have the spring always in contact with the coupling-hook, and in the rea-r ot' the fulcrurn or of such hook, so as to keep its forward end from rising, and allowing the coupling-link to pass rout of the buffer when the cars are in motion.

We have described only one spring, and its application to one side -of the buffer, but it is our intention to use two, one upon each side thereof.

Having thusxlescribed our invention,

What we claim,and desire to secure by Letters Iaty lent, is-
